What are the benefits of using
variadic functions
void fun(int i, ...);
instead of passing a pointer to an array?
void fun(int i*);
When are variadic functions preferred?
You have to explicitly create the array first. In addition, it would be problematic if you wanted to specify parameters of different types.
Variadic functions do not require creating any array and they can deal with different types.
As an example, I could not bare to use the
printf-functions if I always had to create some array first.On the other hand, in most cases it’s just a form of syntactic sugar, I suppose.
